I get javaScript error when my model return nullable Int.  I use MissingValues(ChartLineMissingValues.Gap) but this didn't fix the issue. I really don't want to show the line when there is no values. If I change my code to return zero it will show the Line at zero. this is not what I am looking for 

Unhandled exception at line 35, column 17304 in http://localhost:28123/Scripts/kendo/2013.2.716/kendo.all.min.js

0x800a138f - JavaScript runtime error: Unable to get property 'value' of undefined or null reference

Hi,

I am also having the same issue.  Following is the code snippet.
List<double?> chartData = new List<double?>(new double?[] { null, null, null, null });
 
List<DateTime> chartTime = new List<DateTime>(new DateTime[] { DateTime.Now.Date,DateTime.Now.Date.AddDays(1),DateTime.Now.Date.AddDays(2),DateTime.Now.Date.AddDays(3)});
 
var chart = Html.Kendo().Chart();
 
chart.Name("MissingGap");
 
chart.SeriesDefaults(seriesDefaults => seriesDefaults.Line());
 
//Add series
chart.Series(p =>
                {
                    p.Line(chartData).MissingValues(ChartLineMissingValues.Interpolate).Name("Stock Market");
                     
                });
 
chart.CategoryAxis(axis => axis.Date().BaseUnit(ChartAxisBaseUnit.Days).Categories(chartTime));
                
chart.ValueAxis(axis => axis.Numeric().Labels(labels => labels.Format("{0}")));
                
chart.Render();
Can you please give us a fix or work-around for this issue.

Thanks,
Suresh

Hi Hristo,

This is working with the latest internal build. Thank you.
By the way, do you know when will be the next official build, which will help me in deciding whether to go with this fix or not.

Thanks,
Suresh
